- Page 5 Please take special note of the following precautions before operating your new preamplifier: • This preamplifier operates at hazardous voltage levels.

(slots in the lid) are not covered or restricted in any way. Also refrain from placing the Plinius Jarrah on top of other electronic equipment to avoid RF interference being introduced to the highly sensitive phono stage circuitry. - Page 7 If your phono turntable has an earth cable, this can be connected to the gold earth post on the back of the Plinius Jarrah. Fit the power supply DIN socket to the back of the Plinius Jarrah. It only fits in one way, and ensure that it is fitted securely.

WARM-UP PERIOD You will find that the Plinius Jarrah will become noticeably ‘warmer’ in sound after being on for a period of time. We usually recommend waiting at least 24 hours before expecting the best quality of sound reproduction from your preamplifier. - Page 9 The Jarrah mini-switches are factory set to a 47kΩ load. Also, switch 1 is set in the on position. This is a 220pF capacitive setting and is usually required for RF suppression. It is not recommended that you turn switch 1 off.

Disconnect the lead from the IEC socket on your Plinius Jarrah. Carefully remove the lid by undoing the six cap screws. Locate the small black phono jumpers to the centre-front of the circuit board. The gain can now be adjusted noting that high gain (factory setting) is set with jumpers to the front position, and low gain is set with the jumpers towards the rear of the preamplifier. - Page 11 F F F F R R R R : : : : Phono RIAA network 20Hz to 20kHz ±0.2dB.
